Gwent's single-player campaign has been pushed back to 2018

The single-player campaign for Gwent, the standalone version of the addictive card game introduced in The Witcher 3: Wild Hunt, has been delayed into 2018.
Aside from giving us an expansive story, The Witcher 3 introduced an addictive card game called Gwent. Gwent gives you and your opponent a set of cards which simulate battles. You must use certain warriors at the right time to win. Gwent got a standalone experience a few months ago but since then many gamers have been asking for a single-player expansion. While this may seem like an odd request, The Witcher lore is so vast that a lot of stories can be told through it.
